Control is by means of a neutral zone or proportional band and is based on the pressure or
temperature sensed in the LP suction (compressors) and HP (condenser) circuits. A special
algorithm balances the run hours of the compressors to distribute the work load uniformly.
The controllers can convert both suction and discharge pressures and displays them as
temperatures.
The front panel offers complete information on the system’s status by displaying the suction and
condenser pressure (temperatures), the status of the loads, possible alarms or maintenance
conditions.
Each load has its own alarm input that is able to stop it when activated. To guarantee the total
system’s safety, there are also two inputs for low and high pressure switches: when these are
activated, the system is stopped.
By means of the HOT KEY the controller can be easy programmed at power on.
The controller can be connected to the X-WEB, controlling and monitoring system, thanks to the
serial TTL output, using the standard ModBus RTU protocol.
4. COMPONENTS RELATED TO THE XC645CX
